StatusBarItem - add support for specifying a list of commands in the hover

[lszomoru]

It would be nice if extensions would be able to specify a list of commands which would then be passed on to the HoverService so that they are rendered in the hover status bar.

This needs to set the related actions options when creating the hover:

vscode/src/vs/workbench/browser/parts/statusbar/statusbarItem.ts

Line 123 in fc03f2b

this.hover = this._register(this.hoverService.setupManagedHover(this.hoverDelegate, this.container, hoverContents));

vscode/src/vs/base/browser/ui/hover/hover.ts

Line 187 in fc03f2b

actions?: IHoverAction[];

I would think this could be proposed new API for the status bar item to have an overload for tooltip:

vscode/src/vscode-dts/vscode.d.ts

Line 7229 in fc03f2b

tooltip: string | MarkdownString | undefined;

Something like:

tooltip: string | MarkdownString | { actions: Command[], content: string | MarkDownString } | undefined

If someone wants to contribute this, opening for help wanted 👍
